hurd: Use __hurd_fail () instead of assigning errno
The __hurd_fail () inline function is the dedicated, idiomatic way of
reporting errors in the Hurd part of glibc. Not only is it more concise
than '{ errno = err; return -1; }', it is since commit
6639cc10029e24e06b34e169712b21c31b8cf213
"hurd: Mark error functions as __COLD" marked with the cold attribute,
telling the compiler that this codepath is unlikely to be executed.
In one case, use __hurd_dfail () over the plain __hurd_fail ().
